1, 060,324. Electrophysical measurement. BECKMAN INDUSTRIES Inc. Feb. 25, 1965 [March 10, 1964], No. 8084/66. Heading G1N. A reference electrode for e.g. pH measurement is made by compressing powdered metal to form a porous unitary body, and immersing the said body in a bath of a molten salt of the metal, preferably under vacuum to remove gas from the pores so that when the vacuum is removed the molten salt is forced into the pores in the body. Ag/AgCl is mentioned as an example. |
